SPECIFICATION forming part of Letterslatent No. 521,02 5,dated J' une 5, 1894. Application tiled ltoyember 24, 1893. Serial No. 491,817. (No model.)

To @ZZ whom it) may concern:

.Be it known that I, JOSEPH .HANDELEL a citizen of the United States, resid-ing at Chicago, mthe county of Cook and Stateof Illinois, have invented a new and useful lImprovement in Box-Blocking Machines, of which the fol` lowing 1s a speclication.

My invention relates to an improved ma-V chine for use in the manufacture of packing boxes, to block off or smooth the sawed edges thereof.

In the manufacture of wooden packing boxes, especially where they are made in large numbers, the pieces which afford the sides, bottom and cover of a boxare cut with saws to the proper dimensions and then fastened, usually by nailing them, around the edges of the pleces which afford the box ends. To tinish the box it is usual to smooth or block off the sawed edges which appear at the sides and ends of the box, and hitherto this has been done with a suitable carpenterrs plane in the hands of an operator. When done byhand the operation is necessarily slow and laborlous; and,1t is my object to provide a machine for the purpose of comparatively simple and durable construction, which shall render the operations of blocking olf boxes quick and easy to accomplish.

In the drawings-Figure 1 is a side elevation and Fig. 2, a broken top-plan view of my improved machine; Fig. 3, a section taken on line 3 of Fig. 1 and viewed in the direction of the arrow; Fig. 4, an enlarged broken section taken on line 4 of Fig. 3 in the direction ot' the arrow; and Fig. 5, a detail plan-section on line 5` of Fig. 4.

The drawings illustrate, what I term a double machine, in which two boxes may be operated upon at once.

A is the frame of the machine which may be constructed of timbers as represented, or 1 t may be of metal which would give to it a lighter and more graceful appearance. Journaled in one end portion of the frame is a shaft B, provided between its bearings with fast and loose pulleys B', and beyond its bearlngs, at opposite ends, with drive wheels B2.

n As the mechanism on one side is a substant1al duplication of that on the other side of the machine, it will be sufficient to describe one mechanism and to designate corresponding parts of the other mechanism by the same reference lletters and numerals.

A and A2 are, respectively, the forward and rear standards forming part of the frame-work A. The standards are preferably grooved 'on f ,their inner sides to aord vertical guides t t,

and rabbeted on their outer sides to aord vertical dove-tail guides s s. Secured upon the upper ends of the standards are brackets r r, provided with horizontal and vertical bearing openings. Journaled at its opposite end-portions in the horizontal bearings in the brackets, is a rotary horizontal shaft q, carrying beveled pinions q adjacent to the inner sides of the brackets, and an operating' crank or hand-wheel Q2 at its forward end. Fitting and sliding in the guides s, are dovetailed guideblocks or brackets p, to which a platform n is fastened at its opposite ends. Vertical threaded-rods or screws m extend through the vertical bearings in the brackets o", and are provided at their Aupper ends with beveled pinions m lwhich mesh with the'pinions The screws m extend through and engage threaded openings in the brackets p.

Turning the hand-wheel q2, rotates the shaftV q and screws m, causing them to slide the brackets p in the guides s-and raise and lower the platform equally at opposite ends. Fitting and moving at opposite ends in the guides t is a vertically sliding guide-frame Z, formed with an upper bar Z and lower bar Z2 having an opening Z3 between them. On the bar Z2 in the opening Z3 is a beveled projection 0r rail Z4. Fitting over and sliding upon the rail Z4 is a carrier-block Zt. A pitman la is pivotally connected at one end to the block Zo and at its opposite endt-o the drive-wheel B2 on the adjacent side of the machin e. Turning of the wheel B2 causes the pitman to move the carrier-block back and forth in the guideframeZ. The frame Z rests at opposite ends upon springs t' confined between the said frame `.and a cross bar t' of the main frame.

Fastened at opposite ends to the frame Z near opposite ends of the latter is a V-shaped rod orV bale h, which at its center is connected pivotally, to the upper end of a rod h. At its lower end the rod h is secured to a foot lever h2. Pressure upon' the lever h2 forces IOC the latter and the frame Z, in its guides t, downward against the resistance of the springs tf; and, when the pressure on the lever is relaxed, the lever and frame are raised to normal position by the action of the springs.

C is a plane of any suitable pattern secured at one side of its stock to the outer side of the carrier block Zt'. The sole of the stock extends in the horizontal plane, and the cutting edge of the ironor bit extends in the direction of the back of the machine, whereby it cuts in the backward stroke. At the standard .A2 is a stop A3, which at its forward side presents a vertical straight edge, and extends at its upper end in a plane a little below the normal plane of the guide rail Z1. t

The machine may be belted at the drive pulley to a suitable drive shaft, and the plane C reciprocated continuously in the guide frame Z. rlhe box to be operated upon is placed upon the platform n against the stop AB and the platform is adjusted, byturning the hand-wheel q2, to canse the upper edge of the box to extend in practice about oneeighth of an inch above the plane of the upper end of the stop A3. In the backward movement of the plane the operator pressesY his l'oot upon the lever to lower the plane and cause its bit to engage and shave off the upper edge of the box. The operator then relaxes the pressure upon the lever, whereby the frame Z and plane are raised, so that the box may be turned to present another edge to the action oi' the plane without interference from the latter in its forward movement.` In practice the box may be turned during each forward movement of the planete present a new edge at each backward movement thereof. After the ends of the boxes have been blocked oil", the platform may be adjusted to the proper elevation for blocking off the side edges. Usually a large number of boxes of the same dimensions are finished, at once, and it is only necessary to change the adjustment of the platform when boxes of other dimensions are brought to the machine. If desired the guides s may be dispensed with, and the screws caused to serve as guides for the platform; and while I prefer to construct my improved machine as shown and described, it may be modified in the matter of details without departing from the spirit of my invention as defined by the claims.

Then desired a single machine may be provided, containing only the mechanism shown at one side of the double machine illustrated, and which will operate upon one box only at a time.

What I claim as new, and desire to secure by Letters Patent, is

l. In a box-blocking machine a plane slipport, in which a plane is mounted to reciprocate, and a box-support, the said supports being adjustable and resiliently yielding one with relation to the other, and lever mechanism connected with one of the supports and operative to move the same against its resilience, whereby the path of the plane with relation to the box-support may be varied, substantially as and for the purpose set forth.

2. A box blocking machine, having in combination a resiliently yielding guide, a reciprocating plane in the guide, a platform to support the box, and lever mechanism connected with the guide for moving it against its resilience to vary the path of the plane, substantially as and for the purpose set forth.

3. A box-blocking machine having, in eombination, a movable spring sustained guide frame, a reciprocating plane mounted in the guide frame, a platform to support the box, and lever mechanism connected with the guide-frame for moving it against the resistance of the springs to vary the path of the plane, substantially as and for the purpose set forth.

4. A box-blocking machine having, in com-` bination with the main frame, a drive shaft, a resiliently yielding guide frame, a plane mounted in the guide-frame and geared to the drive shaft to reciprocate in the guide frame, a platform, to support the box, raising and lowering mechanism for the platform, and lever mechanism connected with the guide-frame for moving it against its resilience to vary the path of the plane, substantially as and for the purpose set forth.

5. A box-blocking machine, comprising, in combination,a frame A,adrve-shaft mounted in the frame, a spring supported guide-frame Z movable in guides in the frame, plane C geared to the drive-shaft and mounted to reciprocate in the frame Z, a platform n, raising and lowering mechanism for the platform, and a foot-lever connected with the frame Z and operative to lower the said frame in its guides against the resistance of its springs, substantially as and For the purpose set forth.
